    “the work with vpn was delivered by other guy, he got other job from me.”

  • image of Joel B. Need Cisco CCIE for firmware support $30.00 USD

    “Just needed him to download two files accessible only to people with Cisco Service Agreements. Sent him the links and he still uploaded the wrong files. Three times. Likely didn't have his own account and instead went browsing. After accepting he repeatedly asked for more money. Wanted $100 to download and transfer two files. There was no surprises, no change in scope, should've been 5 minutes. I'm only writing because it was such an irritating experience for something so simple.”

    “Ahmed did deliver the project in full of acceptable quality. Unfortunately he had to deal with some unforeseen circumstances and was unable to deliver in the time agreed upon. As time is an important factor for me, I would have preferred early clear communication to ensure I could have the project completed sooner. However, it was a difficult time for Ahmed so I understand. Overall, quality of work was great.”
